Scent-based spoilage sensing refrigerator

1. A refrigerator, comprising:

a computing device that comprises a processor and a memory;

a compartment having an interior space configured to contain a food item;

a chemical sensor mounted within an interior of the refrigerator and configured to at least measure an amount of a chemical related to spoilage of the food item in the compartment; and

an application stored in the memory that, when executed by the processor, causes the computing device to at least determine that the amount of the chemical related to the spoilage of the food item exceeds a chemical threshold, the chemical threshold is based at least in part on an airflow rate associated with the compartment of the refrigerator.

2. The refrigerator of claim 1 , wherein the chemical sensor is further configured to at least report the amount of the chemical related to the spoilage of the food item to a remote computing device.

3. The refrigerator of claim 1 , wherein the refrigerator further comprises a network interface configured to report the amount of the chemical related to the spoilage of the food item to a remote computing device.

4. The refrigerator of claim 1 , further comprising a camera configured to capture an image of the compartment.

5. The refrigerator of claim 4 , wherein the camera comprises an infrared camera.

6. The refrigerator of claim 1 ,

wherein the application, when executed by the processor, causes the computing device to at least:

determine a measurement interval for the chemical sensor to take a plurality of measurements based at least in part on at least one of: an internal temperature of the refrigerator or the airflow rate for the compartment in the refrigerator.

7. The refrigerator of claim 1 ,

wherein the

chemical threshold associated with a spoilage indication is further determined based at least in part on a quantity of food items in the compartment.

8. The refrigerator of claim 1 , wherein the compartment comprises a first compartment that is connected to a first airflow spine of the refrigerator, and further comprising:

a second compartment that is connected to a second airflow spine of the refrigerator, wherein the second airflow spine has an airflow that is isolated from the first airflow spine of the first compartment.

9. A refrigerator, comprising:

a computing device that comprises a processor and a memory;

a compartment having an interior space configured to contain a food item;

a chemical sensor mounted within an interior of the refrigerator; and

an application stored in the memory that, when executed by the processor, causes the processor to at least:

determine a threshold amount based at least in part on an airflow rate associated with the compartment;

perform, via the chemical sensor, a measurement of an amount of a chemical related to spoilage of the food item in the compartment; and

determine that the amount of the chemical related to the spoilage of the food item exceeds the threshold amount.

10. The refrigerator of claim 9 , wherein the application, when executed by the processor, further causes the processor to at least:

determine a measurement interval for the chemical sensor to take a plurality of measurements based at least in part on at least one of: an internal temperature of the refrigerator or an amount of airflow in the refrigerator.

11. The refrigerator of claim 10 , wherein the application, when executed by the processor, further causes the processor to at least:

compare the amount of airflow in the refrigerator and an expected airflow in the refrigerator as indicated in a refrigerator profile.

12. The refrigerator of claim 9 , wherein the application, when executed by the processor, further causes the processor to at least:

determine the threshold amount associated with a spoilage indication based at least in part on a quantity of food items in the compartment.

13. The refrigerator of claim 9 , wherein the chemical sensor comprises a network interface and is further configured to at least report the amount of the chemical related to the spoilage of the food item to a remote computing device.

14. A refrigerator, comprising:

a chemical sensor mounted within an interior of the refrigerator; and

a computing device that comprises a processor and a memory, wherein the processor is configured to at least:

determine a presence of a food item in an interior space of a compartment of the refrigerator;

determine a threshold amount based at least in part on an airflow rate associated with the compartment of the refrigerator;

cause the chemical sensor to measure an amount of a chemical related to spoilage of the food item; and

determine that the amount of the chemical related to the spoilage of the food item exceeds the threshold amount.

15. The refrigerator of claim 14 , wherein the processor is further configured to at least:

determine the threshold amount based at least in part on a quantity of food items in the compartment or a volume size of the compartment.

16. The refrigerator of claim 15 , wherein the processor is further configured to at least:

adjust the threshold amount for the compartment based at least in part on a change in the quantity of food items in the compartment.

17. The refrigerator of claim 14 , wherein the processor is further configured to at least:

determine a measurement interval for the chemical sensor to take a plurality of measurements based at least in part on at least one of: an internal temperature of the refrigerator or an amount of airflow in the refrigerator.

18. The refrigerator of claim 14 , wherein the processor is further configured to at least:

determine a measurement interval for the chemical sensor to take a plurality of measurements based at least in part on a comparison between an amount of airflow in the refrigerator and an expected airflow for the refrigerator.
